display several pages when past multi-value parameter in one report

Jackie

Hi,

Can someone help me how to display several pages, when receive a multi-select-value parameter.

for example, when customs select one like "1", then show one page, just for "1". When select multi-value like "1,2" , then I want to show two pages, one for "1", another for "2".

I may process the multi-value in Before Factory, split "1,2" to "1","2", but have no following ideas.

happy to receive any idea.

p.s. I am working on BIRT 4.2.0

best regards.

Hi Jackie,

Can you give more details about what you are trying to do?
Is there a data set that needs to be filtered based on the selected values? And then all records that have a data set column = 1 need to be on page 1 and records that have that data set column = 2 need to be on page 2?

Hi Hans, 
firstly thank you very much. 
Sorry having not discribed the aim clearly. I want to print several times with different report font color. 
I have attached my report design file. In the BeforeFactory, I handle the multi-selected-param "use". My report has handled the multi-select-value as a single value, like use = reportContext.getParameterValue("use")[0]. but that not reach my aim. 
if uses=[1,2,3], how can I do the following loop, print three times with different font color 
for(i=0; i<uses.length; i++){ 
print uses.length times report 
} 
 
regards

Hi Jackie, 
 
I'm not aware of any possibility to repeat a page, but you could do it like this: 
- create 7 tables, each with a different font color, each (except the last one) with Page Break After = Always 
- for each table create a visibility expression like this: 
<pre class='_prettyXprint _lang-auto _linenums:0'>if ((params["use"].value).indexOf("1") >= 0)
false
else
true</pre>
- replace "1" by "2" for the second table, by "3" for the third table and so on...

Hi Hans,

Thanks very much for your advice, with your help I can reach the aim.

But there is another problem, the page is too large. Can I loop it just when printing ?

Best regards
